• 論文の詳細を見る

• Numerical analysis is carried out for soliton modes in a one-dimensional easy-plane ferromagnetic lattice with an in-plane magnetic field. Lifetime of the sine-Gordon soliton is studied as a measure of difference between the lattice model and the continuum one. Three oscillatory modes are observed as collective motions of spin vectors, which are not in the continuum media. Lattice discreteness is found to be essential to the soliton dynamics in the solid material.
